You, Ariel, and your sister, Belle, have always been close. You are all each
other had, as you grew up in an orphanage and do not remember your parents.
One day, however, Belle goes missing. Thanks to the bond you share, you know
she is not dead. She is all you have. You must find her and learn what
happened.

Sister’s Secrecy: Arcanum Bloodlines is an adventure game with hidden
object and mini-game puzzles. You use your mouse to select items on the
screen, select the hidden object items from the list, and play mini-games.
From your inventory, you can use the items you gathered to solve other
puzzles. If you choose, instead of doing the hidden object puzzle, you can do
a match-three puzzle. You just go to the hidden object screen and click the
circular item on the bottom left.
